REVOLVING BOOT-HEEL.

SPECIFICATION forming part of Letters Patent No. 253,348, dated February 7, 1882.

' Application filed July 26, 1881. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM CRAIG, of Jamestowm'in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in Revolving Boot- Heels; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a longitudinal vertical section of a boot provided with my revolving heel. Fig. 2 is a vertical cross-section at right angles to Fig. 1. Fig. 3 is'a bottom view of the heel with the bottom lifts removed, and Fig. 4 is a perspective view of the heel pivot or spindle detached.

.Similar letters of reference indicate corresponding parts in all the figures.

Myinvention contemplates an improved construction of revolvingheels for boots and shoes, as hereinafter more fully set forth, and particularly pointed out in the claim.

In the annexed drawings, A represents the heel portion of a gaiter, boot, or shoe, as the case may be, provided with myimproved heel. The latter is made in two sections-viz., an upper section or top part, B, which is of circular shape, and nailed to the insole in the usual manner, and a circular revolving disk or sec tion, 0, built up of a suitable number of lifts or taps to make it of the requisite height.

The pivot or spindle upon which the revolving heel-disk O is secured is composed of four parts, cast in one piece, of iron, brass, or other suitable metal-via, a cylindrical middle part or shank, D, a circular plate or disk, E, a cen trally-projecting lug, F, and a cross-head, Gr,

' at the lower end of the shank, which is made ing a slot, d, sufficieutly large to admitof the insertion of the cross-head G, after which the lifts are turned to one side, so as to interlock with the cross-head, as shown in Fig. 3, after which they are secured by nails h, driven into the part 0 through the end notches, g g,in cross-head G. The heel is then finished by placing the bottom lifts, 1', over the cross-head and heads of the nails h h, said lifts being fastened by nails or screws k. The bottom part, i, is recessed to receive the cross-head Gr, so that the whole part 0 will present a neat and finished appearance.

The circular plate E of the central spindle should be held or clamped with suflicient firmness between the lifts of the top part, B, between which it is inserted, to prevent it from turning too easily, so that the rotary part G,

which is rigidly connected to the spindle, willnot be likely to turn accidentally or of its own' account. As the heel becomes worn on one side it may be turned with the hands so as to bring afresh part to bear, and in this manner the heel will be worn evenly all around, all that is necessary to keep it in perfect repair being an occasional renewal of the bottom lift i.

liaving thus described my invention, I do not claim broadly a revolving heel, as I am well aware such have been made before; but

What I claim as my improvement, and desire to secure by Letters Patent of the United States, is

The combination, in a revolving heel for boots or shoes, of the stationary part B, having the central recess, f, and chamber a, spindle D, having the top plate, E, provided with the central lug, F, and notched bottom crosshead G, and revolving part O, attached permanen tly to the spindle D, substantially as and for the purpose herein shown and described.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

WILLIAM CRAIG.
